Whats is PET Functional Film ?
PET functional film, widely used on the surface of glass and multilayer circuit substrate, which get the circuitry insulated and substrate surface protection.
The difficulty of the PET film.
- High density precision circuits with minimal line spacing
- Easily creepage prone
- Signal crosstalk
- Limited pressure resistance
The solutions
Ultraviolet picosend laser machine, with cold processing, Ultraviolet picosend laser could score nicks with micron-level precisions, which called Shallow Etching Modification, without substrate impenetrable, which could cut off transversing conductive path, to avoid creepage, meanwhile completely solve the problem of signal interface.
